forex trading

Many U.S. and international companies
provide online trading software and
services for individuals (traders)
who want to speculate on the exchange
rate differences between two currencies.
In doing so, these speculators buy
or sell currencies with the objective
of making a profit when the value of
the currencies changes in their favor,
whether those fluctuations derive from
market news, supply and demand principles,
or geo-political events taking place
throughout the world. In addition, the
forex market is available to trade 24
hours a day, 5.5 days a week, so
customers can trade at nearly any
time, not just when an exchange is open.
